Polytetrafluoroethylene (PTFE) is a thermoplastic resin that is practically resistant to all fluids. Of all our diaphragm materials, it is the most chemically resistant. PTFE is non-elastic, limiting its use in certain applications. PTFE can be used with media reaching very high temperatures up to 260° Celsius

Benefits of PTFE Molded Gasket material:

• Extremely chemically resistant—often used with heptane and methyl chloride
• Extremely heat resistant (recommended for 39 to 500°F / 4 to 260°C)
• Extremely steam resistant

Weaknesses of this material

• Not really an elastomer—it has cold flow issues that can result in leakingot really an elastomer—it has cold flow issues that can result in leaking
• It is expensive
• It is harder to work with during maintenance

Industrial products made with PTFE fluoropolymer resins have exceptional resistanceto high temperatures, chemical reaction, corrosion, and stress-cracking. The propertiesof PTFE make it the preferred plastic for a host of industrial applications anddifferent processing techniques.There are different types of PTFE grades available:

Glass

• The most common filler, minor effect on electrical properties, increased abrasionon mating Wmetal surfaces.

Carbon

• Low abrasion and wear, good deformation and extrusion resistance.

Bronze

Very high wear resistance and load bearing capability. Poor chemical resistance

• Very high wear resistance and load bearing capability. Poor chemical resistance
